PROBLEM TO BE SOLVED: To provide a pigment that has a stronger blue taste and a higher jet-black property than before.SOLUTION: An unconventional jet-black pigment with a strong blue taste can be provided by using, as a pigment, carbon nanotubes produced by a chemical vapor deposition method, in which a gaseous carbon-containing compound and a carboxylic acid palladium catalyst are brought into contact with each other at 500°C-1200°C. |
